“…The CEA approach integrates the distribution of a vegetation type, typically derived from remote sensing, with mapped current climate and projected future climate conditions to determine the climate envelope of that type and assesses the level of climate change for each pixel of that type under future conditions (Thorne, Boynton, Holguin, Stewart, & Bjorkman, 2016;Thorne, Choe, Boynton, et al, 2017;Thorne, Choe, Stine, et al, 2017). CEA differs from climate impact approaches that predict potential range or movement, such as species distribution models, in that CEA is an in situ approach that predicts the climatic shifts within a set area between time periods; it does not predict where species will shift in order to maintain an optimal climate envelope (e.g., Phillips, Anderson, & Schapire, 2006;Thorne et al, 2013), nor does it predict where or how fast a given set of climatic conditions will move (i.e., climate change velocity; Ackerly et al, 2010;Dobrowski & Parks, 2016).…”
